To all whom it may conc-ern Be it known that-I, FRANK H. ALLEN, a citizen of the United States, residing at Donaldsonville, in the parish of Ascension and State of Louisiana, have invented certain new and useful Improvements in Gasolene Traction-Engines; and I do hereby declare the following4 to be a full, clear, and exact description of the invention, such'as will enable others skilled in the art to whichit appertains to make `and use the same.

My invention relates to improvements in motor tractors, and it consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention is to provide an improved motor tractor having a short wheel base and provided with highly ad vant-ageous guiding and turning means.

A :further obj`ect,of my invention is to provide an improved motor tractor especially'adapted for plows or other cultivator implements. which will operate eliciently for cultivating rows of sugar cane, or other tall plants.

In the accompanying drawings forming a partof this application and in which similar reference symbols indicate corresponding parts in the several views Figure 1 is a side elevation, illustrating one embodiment ofmy invention; Fig. 2 is a rear elevation, thereof, with the upper framework omitted; Fig. 3 is a plan, view of the construction shown1 in Fig. 2; Fig. 4 is a detail rear elevation, illustrating a modified construction; Fig. 5 is a fragmentary lplan view ofthe construction shown at the left hand of Fig. 4; and Fig. 6 is a fragmentary plan view of the rear end'of the upper framework and roof shown in Fig. 1.

Referring to the drawings, 1 indicates the bed frame, or body, of a tractor provided `rwith a front axle 2 having .an upwardly arched intermediate portion 3 for clearing rows of tall plants 'such as sugar cane; a pair of rigidly connected traction.

ground wheels 4 and sprocket wheels 5 being journaled on the respective ends of said axle.

A suitable motor 6 is carried by the tractor body with its drive shaft 7 connected to a differential transmission ear 8; the independent sections 9 of the di erential shaft being journaled on the body 1 and carrying sprocket pinions 10 connected to the sprocket wheels 5 by chains 11, Each of the independent shafts 9 is provided with a brke drum 12 adapted to be engaged by a shafts 9 can be checked `to any degree or completely stopped independent of the other o'f said shafts 9. This provides a highly advantageous and elicient means for guiding the tractor, and enables short turnings to be made for guiding the tractor from one row of plants to the next adjacent row.

A bolster 15 is centrally supported on the tractor body l by a king pin 16 and provided with an arc-shaped plate 17 held in engagement with said tractor body b v a strong spring 18; the king pin 16 extending loosely through a slot in said plate 17 and a flaring opening in said bolster for permitting slight rocking of the latter. The bo1- ster l5 carries two lateral frames provided with thrust bearings 19 for the heads 20 of the yokes 21` on the lower ends of vertical spindles 22; said vyokes carrying guiding ground wheels 23 and follower guide wheels 24a. Said lateral frames are provided with pins 69 engaging guiding slots 70 in the tractor body. The upper ends of the vertical spindles 22 extend loosely through clutch membersv24 supported on the tractor body in position for coperation with shiftable clutch members splined on said spindles The loosely mounted clutch members 24 are provided with cranks 26 connected by a link 31, and to which are connected chains 27 wound in opposite directions on the drum 28; said drum being provided with a Worm wheel in mesh with a worm 29 on a manually-operated steering shaft 30. This provides convenient and effective means for simultaneously rotating the two clutch members 24. The splined clutch members 25 are provided with annular grooves for receiving the pins. 32 of gimbal rings 33, which latter 4are provided with arms 34 clamped to a vtransverse shaft 35 on, the tractor bed. The steering shaft 30 is connected by a universal joint 36 with an extension 37 provided with a hand wheel 38; said extension 37 being clamped by an arm 39 to the transverse shaft 35, to provide convenient means for rocking saidshaft to shift the splined clutch members 5 into and out ofengagement lwith the loosely mounted clutch members 24. In this improved constr'fction, when the clutch members 25 are raisl from g means whereby the rotation of either of theengagement, with the u loosely mounted clutch members24, the .vertical spindles 22 are en- .tirelxvv free to turn independently for perf dsaid inner and outer mitting the guiding ground wheels carried therebyv to 'track in the furroivs. On the other hand, when the clutch members 24 and 25' are shifted into engagement, the vertical spindles are locked together and can be simultaneously.rotated for shifting the' guide ground wheels 23 and 24a by 'turning the hand 'WheelBS to rotate4 the winding drum 28.4' 'f V Guter draft rods 40 are pivoted at 41 to plates 42 on the tractor bed in coperative relation with similar inner rods 43 swingingly connected to the arched axle portion rods being connected by cross clevises for plowsor other cultivatorimplements.

The tractor bed is provided with an upy per framework 46 carrying roofing 47 and having a transverse shaftv 48 vjournaled therein; said. shaft having a series of l ysheaves 49 splined thereon and carrying position for coperation lwith shiftable clutch members 56 splined on said spindles 22; said loosely mounted clutch members 54 being provided with cranks 57 connected by tension operative draft v bars 44 and carrying apertured plates to'constitutef" y I have illustfate 'through said tractor ed on a link 58. Q ()ne of the clutch members 54 is provided with a Worm Wheel 59 in mesh with va worm 60 on a steering shaft .61. The splined members 56 aie provided. with annular grooves for receiving the pins of gimbal rings 62, which latter are provided with arms 6 3V clamped' to a transverse shaft l'64 journaled on said lateral bolster frames 55.

The steering shaft 61 is connected by a universal joint 65' with an extension 66 provided with a hand Wheel 67; said ex- 66 beirgfc'lamped by an arm 68 to the transverse shaft-64, to provide convenient means for' rocking said shaft to shift the spilied clutcnmembers 56 into and` out ith `the loosely mounted clutch rerilie I q v arid described preferred and satisfactory constructions, but changes could be made Within the spirit and scope of my invention.'

I claim: In amotor tractor, .the combination of a tractor body, albolster, a slotted arc-shaped plate on said bolster -rockingly engaging said tractor boel-y, a king pin extending body and bolster and through the .slot f said plate,a spring engaging said bolster for vieldingly maintaining said'arc-shapedvplate in rocking engagement with said tractor bed, pins mountthe sides of the rocking bolster, and

guides on said tractor said pins for confining ythe movement of said rocking bolster to swing in a vertical lane.

In testimony whereof, I aiix mysignature, in presence of two Witnesses.
